Description

Air gunjet spraying device
The present invention relates to carried out the air gun device of coating spraying usefulness by spray.
Fig. 4 is existing air gunjet spraying device, and its structure is as described below.11 is the Handheld Division of air gun, 12 is operating portion, 13 is nozzle body, on Handheld Division 11, be provided with compressed air suction inlet 14, trigger adjusts button 15 and compressed air is adjusted button 16, on operating portion 12, be provided with trigger 17, paint can 18 is installed on the nozzle body 13 by pipeline 19 in addition, when using compressed air hose 20 is connected on the compressed air suction inlet 14, pull trigger then, compressed air is through the air ejiction opening 13a ejection of necessary path from nozzle body 13 like this, and the spray coating liquor in the paint can 18 ejects through the nozzle 13b of piping 19 from the center by the attraction effect of air at this moment.
Though the spraying of above-mentioned spray coating liquor has certain injection direction, the influence of the wind around being subjected to etc. can fly around, and Here it is makes spraying irregular colour, the low reason of spray efficiency.
In order to address the above problem, air gunjet spraying device of the present invention is to constitute like this: with portable pot type spray gun device in the peripheral direction that intersects vertically of nozzle body the plectane body of ring-type is installed, inboard at this plectane body, uniformly-spaced be provided with several through holes that run through its back side and front, and also uniformly-spaced being provided with the compressed-air actuated nozzle of ejection in the outside, the compressed air of this nozzle ejection can surround spray coating liquor.
Therefore, by uniformly-spaced being arranged on several nozzles of the external side of plectane, available compressed air surrounds the periphery of ejection spray liquid, makes the spraying that is about to diffusion along straight ahead, the unlikely influence that is subjected to crosswind (even moving of hand also can produce crosswind under calm state because in the operation).
Described ring-type plectane body forms the inclined wall that horn-like expansion is opened from its endoporus towards the front, for this inclined wall, be penetrated with several through holes in addition.
According to aforesaid structure, by above-mentioned through hole, suck external air from the back side of ring-type plectane body, and make speeding up of paint spray, thereby improve deposit efficiency.
In addition, spray compressed-air actuated nozzle, with respect to the spray coating liquor spray centerline of nozzle body, install at the inclination angle that roughly is 1 °～10 °.
According to aforesaid structure, form spiral helicine air curtain from the compressed air of the nozzle of the external side of ring-type plectane ejection, therefore be involved on one side from the spray liquid of nozzle body ejection and the spraying of diffusion thereof, an edge straight ahead, thus can prevent the influence of crosswind effectively.
In the reality,, spray liquid is spread to periphery, environment is polluted, the ADHESION OF PAINTS rate is reduced to below 50% if there is the wind about several meters.And the present invention can prevent the above-described problem from occurring reliably.
Because the particle rapidity from central authorities to the edge is evenly distributed, so the outline line of the graphics shape of spraying face is very clear, mould is evenly distributed, and can prevent to spray mottled or produce the drip phenomenon, thereby improve coating quality.In addition, except can eliminating adhering to loss, improving spray efficiency and the economy of spray coating liquor, can also be by above-mentioned helical form air curtain, the problem of rebounding of generation when solving existing apparatus and spraying in corner portion.
Below with reference to the description of drawings embodiments of the invention.
Figure 1A is the stereogram of the plectane body that uses among the present invention;
Figure 1B is the plectane body that uses among the present invention sectional view along the X-X line among Figure 1A;
Fig. 2 is the stereogram after above-mentioned plectane body is installed;
Fig. 3 is the operation instruction figure of Fig. 2;
Fig. 4 is the stereogram of existing apparatus.
1 is the plectane body that uses among the present invention, and it is made by the synthetic resin material, forms ring-type.And its internal diameter 2 is identical with the external diameter of the nozzle body 13 of aforementioned portable spray gun, is installed in the periphery of nozzle body 13 as described later.
Above-mentioned plectane body 1 forms the inclined wall (m) that horn-like expansion is opened from the endoporus 2 that nozzle body 13 is installed to the front of wall thickness width (m), and also equally spaced is provided with several extend through the front, surround endoporus 2 from the back side through hole 3 on this inclined wall.
The outer peripheral face of plectane body 1 forms narrow inclined wall (n) in the front towards the wall thickness width, locating with being the place (k) that inclined wall (m) that horn-like expansion opens converges, equally spaced be provided with several and spray compressed-air actuated nozzle 4.In addition, 5 is the compressed air ingress pipe that is arranged on the back side of plectane body 1, and 6 is the compressed air channel in the plectane body 1.
The compressed-air actuated nozzle 4 of the above-mentioned ejection parallel lines of the center line of nozzle body 13 (O) relatively rocks, and produces certain angle of inclination, promptly roughly is 1 °～10 ° tilt angle theta.Encasing rotatably in full week of the coating jetting fluid 7 that nozzle by this inclination can eject nozzle body 13 from periphery, thus can prevent effectively that spray coating liquor from dispersing to periphery.
When the plectane body 1 of said structure is installed on the air gun, as shown in the figure, be provided with arm 8 at the compressed air suction inlet 14 of air gun, the two links together by aforementioned compressed air ingress pipe 5 and flexible pipe 9.10 for being installed in the switch valve on the flexible pipe among the figure.
When spray coating liquor is sprayed, one pulls the trigger 17 on the operating portion 12, spray coating liquor in the paint can 18 is just from spray nozzle part 13 ejections, and the present invention cooperates above-mentioned existing operation, open switch valve 10, utilize the nozzle 4 ejection compressed air of this switch valve, will around the spray coating liquor of said nozzle body 13 ejections, surround, make that the spray coating liquor of ejection is unlikely to spread to periphery from the neighboring of above-mentioned plectane body 1.
Along with the compressed-air actuated injection from said nozzle 4 ejections, the air of outside inwardly flows into by the through hole 3 that is located on the plectane body 1, and this not only makes the suitable miniaturization of coating jetting fluid of spraying from nozzle body 13, also can improve the adhesive force of its flow velocity and spray coating liquor.
In addition, in the present embodiment, making the back side of the nozzle 4 on the periphery that is arranged at plectane body 1 be formed centrally narrow inclined wall (n) in the place ahead, is not produce eddy current for the posterior dorsal at each nozzle 4.
The compressed air squit hole of said nozzle 4 is made and roughly is 1 °～10 ° inclined at inclination angles, be in order to produce rotating flow corresponding to the spray coating liquor that sprays from central portion, promptly encase the periphery of spray coating liquor with rotating flow, prevent the spray coating liquor dust formation and to around disperse, thereby make spraying evenly, do not have mottledly, spraying operation is respond well.
In addition, though considering tilt angle theta is tilted to the right or is tilted to the left, but relation because of earth rotation (Northern Hemisphere), be tilted to the left better, be arranged on plectane body 1 the inboard through hole 3 be arranged on the compressed-air actuated nozzle 4 of ejection of periphery preferably not on same radioactive ray, be that nozzle 4 preferably staggers with through hole 3, be positioned at the centre of the through hole 3 of through hole 3 and adjacency.
